Checked C adds static and dynamic checking to C to detect or prevent common programming errors such as buffer overruns and out-of-bounds memory accesses. The goal of the project is to improve systems programming by making fundamental improvements to C. This repo contains sample code, the extension specification, and test code.
- For a quick overview of Checked C and more information, see our Wiki.
- The PDF of the specification is available here.
- Compilers are available here.
We presented a research paper on Checked C at the IEEE 2018 Cybersecurity Development Conference: "Checked C: Making C Safe by Extension". The paper describes the key ideas of Checked C in 8 pages.
